The selection of African elephants can be considered stabilizing selection. Stabilizing selection occurs when the average phenotype is favored, and extreme phenotypes are selected against. In the case of African elephants, traits such as tusk size and body size may be under stabilizing selection, as individuals with average-sized tusks and bodies are more likely to survive and reproduce. On the other hand, directional selection may also be at play in certain traits of African elephants. Directional selection occurs when one extreme phenotype is favored over the other, leading to a shift in the average phenotype over time. For example, if there is increased poaching pressure on elephants with larger tusks, this could lead to directional selection favoring individuals with smaller tusks. Overall, the selection of African elephants likely involves a combination of stabilizing and directional selection, depending on the specific traits and environmental pressures at play. **
